jeremyn Posted July 31, 2016 Share Posted July 31, 2016 I am not a science guy, but more likely what appears as random jumpiness is probably the indicator (umm) indicating small changes in pitch. I'd imagine minute defects in strings, moving the guitar slightly, etc would all cause this. This is true, but the pitch instability of the string is not randomly jumping all over the place. You can see clearly with a strobe tuner the pitch 'wobble', and that wobble is easily seen as averaging around a central pitch. The average changes as you turn the tuning machine, but the string still varies around the central pitch. This is normal, and is the physics of the string. However, the Helix indicator jumps around erratically and it takes longer to determine the average point. It still is usable, and allows the guitar to be tuned way more accurately than the pre-V2 tuner, but it's a bit nasty to look at. Think of the string pitch invariance as a violinist's vibrato. The vibrato will sound out of tune if not centred around the correct pitch. A strobe tuner will show the pulsing vibrato as a nice low frequency movement around the centre pitch. The Helix tuner shows random points of that movement. Reminds me of my first attempt at making a string vs sine pitch comparison back in the '90s for my first semester DSP course. I fixed the issue before submitting. This is not rocket science. Is it usable? Definitely. Thanks Line6 for fixing the tuner so I can use it to tune my guitar accurately. Can it be made more aesthetically pleasing (less jumpy)? Yes to that too. Quote Link to comment Share on other sites More sharing options...
